U.S. personnel, along with contractors, are taking apart military vehicles at Bagram Airbase.

The job is a huge logistical challenge because of all the equipment that has accrued there in 10 years of war.

"We are right now at the beginning of the process," said Brig. Gen. Steven Shapiro, U.S. Army. "The President made the announcement in the State of the Union and so right now we have a plan. And so units are starting to come in right now to drop off their property and starting to go home right now. We think we'll see a bigger surge at the end of the summer but we are very confident the we have got the processes in place to do this."
